Fat City (95% coverage) In December, to the delight of many __________ and the ______ of many doughnut lovers, the New York City Board of Health voted to ban artificial trans fats from restaurants, school cafeterias, pushcarts, and almost every other food-service establishment it oversees, which includes most everything except hospitals. Trans fats don’t occur naturally in the things people like but feel guilty eating, or at least not at high levels (there are small proportions in the fat in meat and dairy products). But artificial ones are plentiful in commercial foods, because they are easy to use, cheaper than natural fats, and keep practically forever. Trans fats are made by pumping _______ gas into liquid fats usually in the presence of _____ so that they will remain solid at room temperature, like butter and ___; and they have the same wonderful properties in pie crusts, cookies, and cakes. Crisco, still _____ for solid shortening made by partial ___________ (of cottonseed oil), soon became the “______” choice for pie crust and fried chicken, making pastry almost as flaky and skin almost as crisp as ___ does.
Fat City (95% coverage) In December, to the delight of many cardiologists and the dismay of many doughnut lovers, the New York City Board of Health voted to ban artificial trans fats from restaurants, school cafeterias, pushcarts, and almost every other food-service establishment it oversees, which includes most everything except hospitals. Trans fats don’t occur naturally in the things people like but feel guilty eating, or at least not at high levels (there are small proportions in the fat in meat and dairy products). But artificial ones are plentiful in commercial foods, because they are easy to use, cheaper than natural fats, and keep practically forever. Trans fats are made by pumping hydrogen gas into liquid fats usually in the presence of nickel so that they will remain solid at room temperature, like butter and lard; and they have the same wonderful properties in pie crusts, cookies, and cakes. Crisco, still generic for solid shortening made by partial hydrogenation (of cottonseed oil), soon became the “sanitary” choice for pie crust and fried chicken, making pastry almost as flaky and skin almost as crisp as lard does.
The Truth About Beauty (98% coverage) Cosmetics makers have always sold “hope in a jar” – creams and ______ that promise youth, beauty, sex appeal, and even love for the women who use them. Over the last few years, the marketers at Dove have added some new-and-improved __________. They’re now promising self-esteem and cultural transformation. Dove’s “Campaign for Real Beauty,” declares a press release, is “a global effort that is intended to serve as a starting point for societal change and act as a ______ for widening the definition and discussion of beauty.” Along with its thigh-firming creams, self-tanners, and hair conditioners, Dove is peddling the crowd-pleasing notions that beauty is a media creation, that recognizing plural forms of beauty is the same as declaring every woman beautiful, and that self-esteem means ignoring imperfections.

How to Address Such Large Amounts of Vocabulary? Why not teach just the most ‘content-ful’ words? Technical Vocabulary ESP vocabulary Academic Support Vocabulary e.g. Academic Word List (Coxhead, 2000) 20
Developing LSP Word Lists “Technical vocabulary ‘is dependent for a full appreciation of its meaning on the meaning of the other terms in the cluster of which it is a member.’” (Godman and Payne, 1981: 37, in Coxhead and Nation, 2001)

A Complete Medical Text Chronic wounds represent a different kind of challenge for wound healing. These wounds do not usually involve a large surface area, but they have a high incidence in the general population and thus have enormous medical and economic impacts. The most common chronicwounds include pressure ulcers and leg ulcers. In the United States alone, these wounds are estimated to affect more than 2 million people with total clinical treatment costs as high as $1 billionannually. Pressure ulcers, characterized by tissueischemia and necrosis, are common among patients in long-term care settings, but patients hospitalized for short-term care settings are also at risk if mobility is impaired. Leg ulcers can have a variety of etiologies. Venous ulcers are the most common, often resulting from dysfunction of valves in veins of the lower leg that normally prevent the backflow of venousblood. Venouscongestion leads to leakage of blood and macromolecules into the dermis, which can act as physical barriers to diffusion of oxygen and nutrients from the
Need Foundation Vocabulary So academic and technical word lists are useful, but cannot replace the need for learners to have a solid foundation of high- and mid-frequency vocabulary in place
How to Address Such Large Amounts of Vocabulary? • These are clearly large numbers of word families to learn • Long-term goal • Most teachers do not have the time, expertise, or opportunity to organize large amounts of vocabulary over a period of time • Most will rely on textbooks to provide the principled selection and instruction of vocabulary
How to Address Such Large Amounts of Vocabulary? A single textbook cannot do the job (even a vocabulary textbook) So are textbook series up to the task? 27

Chilean Case StudyConclusions Textbooks do not match Ministry goals No obvious approach to vocabulary selection or recycling Ministry gives size goals, not specific word lists Publishers given no guidance as to what words to use Different publishers do not liaise with each other to build coherent program 37
What Does It Mean to Know A Word? Form Spoken form Written form Word parts Meaning Form and meaning Concept and referents Associations Use Grammatical functions Collocations Constraints on use (register, frequency…) (Nation, 2001: 27) 39
Lexical Organization “Vocabulary size is not a feature of individual words: rather it is a characteristic of the test taker’s entire vocabulary.” (Meara and Wolter, 2004: 87) Size is a feature of the overall lexicon 40
Lexical Organization Nature of the Lexicon must be connected with vocabulary knowledge Better connected and more highly organized lexicons should relate to more vocabulary knowledge 41
Automaticity Should also lead to faster speed of access and use Fluency 42
How to Facilitate this Complex Learning for Large Numbers of Words? Incidental Learning Explicit Intentional Learning 43
Incidental Learning Many practitioners believe that all necessary vocabulary can be learned incidentally simply by being exposed to, and by using, language 44
Incidental learning does occur in L2 (Reading) Do Things Fall Apart?(Pellicer-Sánchez and Schmitt, 2010) Nigerian language Ibo Spelling recognition: (2-4)=16% (10-17)= 85% Word class recall: (2-4)=7% (10-17)= 54% Meaning recognition: (2-4)=33% (10-17)= 80% Meaning recall: (2-4)=5% (10-17)= 48% 45
Incidental learning does occur in L2 (Listening) (Van Zeeland & Schmitt, 2013) 46
Problem: Incidental learning is limited by amount of exposure It takes at least 8-10 reading exposures to develop an initial form-meaning link and more for meaning recall knowledge (even more for listening) Other word knowledge types (e.g. collocation, register, derivative forms) will likely take many more exposures Most L2 learners do not read enough to ensure this number of repetitions (Cobb, 2007) SO incidental learning is useful, but not sufficient 47
Intentional learning Virtually all research shows that intentional learning with an explicit focus on the target linguistic features results in learning that is Stronger More durable More consistent among learners Productivemastery seems to come mainly from productive engagement 48
Is Knowledge of the Form-Meaning Link Enough? Learning a word might require more than just learning its meaning and form For receptive use, perhaps a meaning-recall level of mastery might suffice See/hear word form and retrieve/recall meaning All of the other ‘contextual’ word knowledge aspects are already in the discourse/text 49
Various Kinds of ‘Word Knowledge’ are Learned Differently But for productive use, learners have a concept in their head, but must produce the appropriate lexical form This requires most (all?) of the ‘contextual’ kinds of word knowledge These contextual aspects (e.g. collocation, connotation, register constraints) are more difficult to teach, and probably require large amounts of exposure to acquire incidentally 50
